Hi ,I am preparing flash the binary using the USB in STM32L412.I checked STM32 USB DFU code. It is working only read. I couldn't write in the STMDFU application.I tried to write to flash ,But i am getting HAL_ERROR and read the FLASH SR register show...

Hi ,I am using bootloader to jump application using QSPI .It is jumping proper in QSPI loader.I faced some timing issue in QSPI. I planned to use SDRAM or internal SRAM1 (0X30000000).In my MCU STM32H750XBH6U single core M7. In bootloader copied image...

I am using STM32H750 MCU . I configured 14 GPIO as interrupt and handle in HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) function. In few GPIO pin number is same and different port .(PA6 , PI6 and PJ6).How to find proper interrupt PIN?

I am using the STM32H750 customized platform .It has connected SPI4 to DAC.SPI4 has supported transfer 16 bit and DAC required 32 bit data.I have transferred 2 times using PWM rising edge and falling edge linked to EXT0 to SPI DMA. I am able to trans...

Our objection is achieving highest frequency and ringing.Requirement:To generate GPIO bit banging on 3 pins in the same port at the frequency 20Mhz.Procedure followed 1) MCU - STM32H750 (Discovery kit)2) Timer Source Clock 240 MHZ and linked to DMA ...

STM32H750 Discovery kit Clock Generation on GPIO Pin @ 10Mhz speed using DMA (Memory to peripheral copy).Timer 5 is configured for 10 MHZ speed to trigger the DMA. In the DMA transfer (Memory to Peripheral) we are using the GPIO PB4 for clock generat...
